OF MAMARO BUTTON-SEWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 783,073, dated February21, 1905. Application filed November 25, 1903. Serial No. 182,590.

To (all whomit may concern: I

Be it known that I, THORVALD O. QUIsT, a citizen of the United States ofAmerica, and a resident of New York city, borough of Brooklyn, county ofKings, State of New York, have invented certain new and usefulImprovements in Button-Sewing Machinesof which the following is aspecification, reference being bad to the accompanying drawings, forminga part thereof. I

My invention relates to improvements in button-sewing machines,andparticularly to I means employed for locating the position of posedbeneath the buttons with respect 'to the goods upon which they are to besewed.

In sewing on buttons it has been customary heretofore to mark the placesupon the goods upon: which they are to be sewed, such marks registeringwith buttonholes with which the buttons when in position are adapted toengage. This marking takes time, and, further,- the marks are sometimeswrongly placed, and, again, the buttons are sometimes sewed onto thegoods in positions out of register with such marks.

In my present invention I have so arranged that that portion of thegoods containing the buttonholes may be superposed upon the portion ofthe goods upon which it is desired to sew the buttons and have providedmeans for receivingthe two pieces of goods so superbutton-clamp and haveprovided means for forcingthe buttonholes open when in the sewingposition, so that the buttons arranged for engagement with saidbuttonholes may. be sewed to the goods through the open buttonholes.

The result of my invention is to cause the buttons and buttonholes toalways correctly register and to avoid the expenditure of time formerlyemployed. Y

A further result of my invention is to deliver the goods in abuttoned-up conditioiwithout further operation. 'Heretofore it has beennecessary to expend time in buttoning up the goods by hand when it hasbeen desired to deliver the goods in such condition. To accomplish theforegoing,'I provide a button-sewing machine with an expandingdevi'cebutton-clamp may then be comprising two relatively movable claws locatedimmediately beneath the button-clamp. These claws are adapted to engageor hook over the sides of a bnttonhole, so that when moved apart theywill force the sides of' the buttonhole open to expose the materialbeneath same.

rial beneath the buttonhole. the stitches for sewing same passing-freelybetween the sides of the said buttonhole.

Myv invention further consists in certain novel details of constructionand combination of parts, as will hereinafter more fully appear.

I will now proceed to describe mechanism embodying my invention and willthen point out the novel features in claims.

In the drawings, Figure l is a View in side elevation of a button-sewingmachine includingmechanismembodying myinvention. Fig 2 is an end view ofsame. Fig. 3 is a par tial end view and a view partially in verticalsection through the button-clamp and buttonhole-expanding device. Fig. 4is a detail top view, on a somewhat-enlarged scale, of certain portionsof the machine, showing the buttonhole-expanding device in operation,certain parts being broken away in order to illustrate better thevarious features of construction and operation.

In the drawings I have shown a conventional form of button-sewingmachinecomprising the usual bed-plate 1, overhangingarm 2, and front head 3.Stitching mechanism is represented by the needle-bar Ki, carrying aneedle 5 and looping or shuttle mechanism 6. 7 designates "a combinedwork-support and button-clam p as a whole. This work-support andbutton-'clamp comprises a carrier 8, a plate .9, an overhanging arm 10,pivoted to the carrier at 11, and a button-clamp 12. N cc- A buttoninserted into and held by the sewed to the mate essary movements areimparted to the carrier 8, and hence to the for shifting thework-support and buttonclamp for presenting the button and material towhich it is to be sewed in the proper stitching positions. Theparticular mechanism for imparting these movements is not illustrated indetail herein, being well known in the art parts supported thereby,

. 3 of the machine.

' stated are then placed and forming no part of the present invention.The plate 9 is'secured to the carrier 8 and forms a "support for thematerial operated upon. The button-clamp-12 comprises an upper rigidplate 13 and a lower spring 14 and constitutes not only a button-clamp,but also a top or presser member for the work-clamp. 1n thedrawings abuttoii is'shown in the position between the upper and lower plates ofthe work-clamp, such button being designated by referencecharacter 15.The arm 10 is provided with an extension 16, to which a link, cord, orchain 17 'is connected. This link, cord, or chain may connect with atreadle or other operating means whereby the arm may be rocked upon itspivotal support 11 to raise and lower the button-clamp. A spring 18operates to move the parts in opposition to pressure applied through thelink, cord.0r chain 17.

An expanding device is arranged beneath the spring-plate 14 of thebutton-clamp 12, such expanding device comprising two relatively movableclaws. In the present embodiment of my invention 1 have shown one of theclaws, 19, as stationary with respect to the button-clamp. The otherclaw, 20, is secured to a sliding plate 21, mounted to slide in guidesupon the upper plate 13 of the button-clamp 12 and spring-actuated, bymeans of a tension-spring 22, in one direction. A bell-crank lever 23,fulcrumed at 24: upon a support 25, secured to the button-clamp plate13, has one of'its arms in engagement with the said slide-plate 21 and.is arranged with its other arm in proximity to and adapted to be engagedby anabutment 26 upon the head When the button-clamp 12 is lifted, theupper arm of the said bell-crank lever 23 will be engaged by theabutment 26, so that the said bell-crank le ver will be rocked upon itssupport and will thereby move the plate 21 forward or in a directiontowardthe line of movement of the needle. The effect of this movementwill be to move the movable claw 20 into line with the stationary claw19. The'parts are shown in these positions in Fig. 2 of the drawings.hen the workclamp is lowered, the bell-crank lever will be disengagedfrom the said abutment .26 and the spring 22 will be permitted to drawthe plate 21 backward. The result of this, will be to move the movableclaw 20 away from the stationary claw 19, as shown in Figs. 3 and 4 ofthe drawings.

In operation material in which buttonholes have already been made issuperposed upon material'toi which it is desired to. attach buttons.The'link 17 is theredepress'ed, lifting the arm 10 and the work-clamp12,-so as to leave a space betweenthelower side of .the button-clampand'the upper surface o the plate 9. Tlie'materials superposed as abovebetween'the plate 9 and the button-clamp 12 with a buttonholelongitudinally in .line. with'the down wardly-probutton-clamp,

jectingportions of the claws 19 and 20, and then slightly lifted, so asto cause the said claws to engage the sides of the buttonhole.

Tension upon the link 17 is now released,per-

mitting the arm 10 and button-clamp to descend, clamping the workbetween the button- .clamp and the plate 9 and a t ..th'e same timemoving the claws 19 and 20 apart in the manner above stated. A buttonbeing now inserted between the plates 13'and 1a of the buttonclamp,thebutton may be sewed to the lower of the two materials.the stitchespassingfreelv between the sides of the buttonhole thus held apart. Figs.3 and T show the parts after the button-clamp has descended and theexpanding device has opened the buttonhole ready for a sewing operation.
